TER, a citizen of the United States, residing at New York city, in thecounty of New York and State of New York, have invented cer-` tain newand useful Improvements in 'Rail- Joints, of which thev following is aspecication.

This invention relates tothe subject ofl` rail joints, and particularlyto that type known.

The standard type o continuous rail joint is characterized by theemployment of joint bars, each of which is rolled to provide an uprightmember or girder interposed between the rail head and the -up er sideofthe rail 4baseqlange, an Outwar ly extending -foot iange overlying thebase flangeof therail, and an inwardly extending rail-supporting basesection integrated with the outer end of' the foot flange and"underlying and bearing against the rail base,`there being a continuousflange-receiving .pocket or space provided between said foot ange andvbase section for the receptionof the base ange of the rail.

v Experience has shownthat it is difl'lcult tosecure absolute uniformityin the rolling of 'rails so as. to insure a perfect 'it of' the joint`bar to the base flange of the rail, inasmuch as the height of the railsbetween the under side ofthe head, and the upper side of the base angefrequently varies to aconsiderable eX- tent so that' when the joint barsare drawn on to the rails, the base flanges ofthe latter engaging theunder surfaces oi4 the outwardly extending foot flanges of the bars,land the upper' surfaces of the inwardly extending base sections thereof,will eXert a Wedging` action'and thereby occasionallycause. a breakageof the joint bars at or about the juncture or (point ot union betweensaid foot --an'ges an base sections. Anyhow, the tendency of the saidwedging action of the base iianges of the rails is to spread theflange-receiving pockets of'the joint bars, that is, to Jforce the railsupporting 4'base sections. downwardly and outwardly, and hence out'ofsu orting Contact with thebases ofthe rails. urthermore, the wedgingaction described has va tendency l edges of the base ianges of the railsthemselves.

It is, therefore, the primary object ofthe and at timesto break orfracture the outer lhe continuous type,by providing la substantial andvample c learancebetween the outer edge' ortionfiof the'bas'eiianges-ofthe rails the foot 4flanges and base sections of thejoint-bars, whilea'tfthe same time providing a construction thatcontributes materially -to- 'the lieXibility and resiliencyfoffsaidbase-sectionsofzthe joint bars l s o that the base secporting `functions'un' er .all conditions. l

As indicated, the ir'ivention'claimedl herein the Acontinuous type ofra1l head 4 ybearing against the under side'oi'thev rail head, and" atthe lower edge of' the iup'- right member or girder 8', each jointbar 1s@esamina-0fof t e continuousjolnt bars Zie so formed with an 'outwardlyextending footv flange 4a overlying the base flange 5 of the railandvhaving integrated with the outer edge portion thereof an inwardlyextending rai]s supporting base section 6 underlying and lbearingagainst therail base', there being a' continuous ,flangereceiving pocket or space -7 provided between said flange 4a and basesection 6 for the reception 'of the base flanges of -the rail. Theseseveral elements are characteristic of the continuous type of joint-barand are embodied in the 'construction shown inboth Fi'gs. l and 2 of thedrawings, but; in Fig. 2 there is illustrated the A'standard -or'conventional construction of S crowded or spread downward so as to bedeflected away from the rail basefwhen applied toa base of`extra;thickness.` When the y joint bars are thus distorted, the railsupporting base sections/only have a bearing at the extreme outer edges"of the base flanges of the rails, as clearl'yshown in Figi 2-.o`f thedrawings, and toobviate this and thepther objections noted, the presentinventioncontemplates the improvei'iistruction in Fig. l of thedrawings.

Referring particularly to Fig. l, it willbe observed that the presentinvention contenif plates rolling and shaping each joint ba'r 2 in sucha manner that the same does not have a bearing-contact with the upperinclinedsurface of the rail flange throughout the entire `width of saidsurface, but, instead, the bar is provided at the bottom edge of itsupright member or girder 3 with an inclined bearing faceS closelycontacting with the inner portion of the upper inclined surface lof therail flange, while the major portion of theunder surface of theroutwardly 'ext nding foot flange 4? of the joint bar is pro ded with aclearanceface 9 disposed at an angle of'materially less degree than theangle of the upper inclined surface of the rail flange, so as toentirely clear not only the extreme outer edge of the rail flange, butalso a considerable 'ofthe foot flange 4 of the j-oirit bar.

portion of the upper surface of said/flangeso that it is impossible forthe outer edge portion of the rail flange to have any wedging actionagainst the said upper clearance face 9 In 'addition to the said up erclearance face 9 of the foot flange 4a of t e joint bar, a distinctiveand important feature of the present invention resides in forming theupper surface ofthe base section 6 of each joint bar with what may betermed an under clearance face 10 arranged in opposite relation to theupper clearance face 9 and disposed benathorgunder the rail base for aconsiderable portion in aan' from the extreme outer edge ofthe railflange. The, said. clearanceface 10-atthe upper side of the base section6' of 'each joint bar is spaced a sufficient distance from the rail baseand the outer edge or corner of therail flange, so as to.entirelyobviate the possibility of s aid flange exerting a wedgingaction'against the base section, such as indicated in Fig. 2, and

bightv of the flange receiving pocket 7 is disposed well beyond theouter edge 'of the rail also ample space to accommodate the adjustmentof the bar upon rails having flanges of different thickness, and hencehaving varyf flanges.

the clearance face l0 terminates, is provided the base section formed atyits upper side with the clearance face 10 is reduced in thickness bythe formation of such face so as to consti- Aconditions met with, thebase supporting sec'- tion ofeach ,joint bar will always vremain in itsnormal position with relation to the other elements ofthe joint, andwill exert an upward springclamping .action beneath and against the railbase. y'

, From the foregoing it is thought that the construction and 'advantagesof the herein described improvement in a' continuous type of jointbarwill b e readily apparent without further description. f
